UNITED STATES PATENT @rrrca RICHARD GLARKSON SCOTT, OF LIVERPOOL, COUNTYOF LANCASTER, ENGLAND.

EFFERVESCENT-BEVERAGE POWDER.

SPECIFICATION forming part of Letters Patent No. 369,368, datedSeptember 6, 1887.

Application filed October .1, 1586. Serial Nu. 215,1?7. (No sporimens.)

It) aZZ whom, it 11mg concern:

Be it known that i, RICHARD CLARKSON Sco'rr, a subject of the Queen ofGreat Britain, residing at Liverpool, in the county of Lancaster, in theKingdom of England, have invented certain new and useful Improvements inCompound for Making Drinks, of which the following is a specification.

This invention has for its object an offervescent drink to be sold inthe pulverulent .form, that shall have the advantages of forming acolored drink and froth from a white powder, (and thus appearing to havea peculiar chemical reaction,) and of being distinctly oxygenizin Theinvention consists in taking the usual constituents of effervescentdrinksa nonpoisonous vegetable acid, such as tartaric or citric acid andan alkaline bicarbonate. These can either be mixed dry or kept separate,the carbonate in one paper or package, the acid in another, and addingto these an oxygenating compound, such as permanganate of potash orchlorate of potash. I prefer the former. It is preferably added in afine powder to the bicarbonate, if the latter be separate from theacids. To the compound, or to either powder, when kept separate, isadded ground loafsugar, with the addition, if desired, of a medicinaldrug-such as Epsom salts-and any flavoring compound or essence,

L such as oil of lemon.

I prefer to use the different ingredients in about the followingproportions, though they may be somewhat varied to suit differentpurposes or tastes, if found desirable to do soviz.,soda bicarbonatedivehundred and twenty parts; acid tartaric, five hundred and twenty parts;cream-tartar, one hundred parts; sugar, (crushed loaf,) three hundredand eighty parts; Epsom salts, one hundred and forty parts; permanganateof potash, one part; fiavoring to taste.

The acids and bicarbonate are taken or mixed together in a dry form inthe usual re spective quantities to effect partial neutralization whendissolved in water. To the mixed powders, or to either separately, isadded the requisite qnantit of sugar, and to these, when thoroughlyincorporated, is added the linelypowdered permanganate of potash. TheHHX' ture is preferably warmed or heated to about 120 Fahrenheit beforeaddition of the permanganate of potash, in order to obtain the thoroughmixture and incorporation oi the ingredients. l inelyground Epsom saltsor other drug intended to be used is then added; also the oil of lemon.or other flflVOlllW. When oxygenating qualities are especially roquired,a quantity of finelyground chlorate of pot-ash about equal to onehundred parts of the above mixture is added. Besides permanganate ofpotash or of soda, other coloring matters can be used. Thus chlorate ofpotash and limetl1yla11iline or other intense coloring matter can beused that can be added in the dry pulverulent form, although most ofthese are poisonous, yet the quantity required to prod nee the requisitecoloring eil'rct is so small that no baneful results follow. I, however,much prefer the permanganate of potash, it being non-poisonous.

I prefer to prepare the compound as one mixture and notin separateparts, though any one or more of the ingredients may be preparedseparately and mixed or combined imnicdiately before use.

It will be understood that while I consider the above-mentionedproportions lhe best, l do not limit theinvention exactly to them,nor toa compound consisting of all of them; but

'W hat I claim as my invention is- 1. The improved process of makingefferveseent-drink powders, which consistsin adding in the dry state toand mixing intimately with any ordinary dry effervescent mixture,powdered soluble permanganate in such limited quantity that its colorshall be masked by the white ingredient, whereby a colorlesseffervescent material is formed which on ad mixture with water forms acolored solution and froth.

As a new article of manulhcture, a eolorless effervescent mixture havingas constituents the ordinary effervescent powder, such as is now sold instores, and powdered alkaline permanganate, the latter in such limitedquantity as to be practically masked when dry by the White effervescentpowder, so that the In testimony whereof I havesigned my name whole hasa white color, but will produce a to this specification in the presenceof two subcolored drink. scribing witnesses.
